Flower Cabochons

First, I want to thank everyone who has helped my friend and me with identifying a LOT of items that came in a 'component box' he purchased. By pointing me in the right direction, I was able to ID many items on my own...something I wouldn't have been able to do without you.

I'm down to 2 items I'm having trouble with identifying. First are these flowers. In the box, there are items marked Made in Japan, Made in Occupied Japan, Made in US Zone Germany and Made in China. A lot of the packages were written on in fountain pen. We've pretty much set a span of 1940-1970. I know...that's a long time, but the best we can do.

These 2 flower cabs weren't marked with a place. The white ones with faded color were marked 'antique'. The other flowers look almost like clay. Or an unglazed porcelain.

I would appreciate any help!
